Simply put enemies needs some pierce resistance and armor buff with regards to their material. Example Liquid/Plastic type enemies should bounce off most Bashing damaging but not cutting/piercing.
The game is already easy enough once you get your skills past 3 and decent stats unless you built your stats to be weak like 6,6,16,10.
If you really think about it armor should reduce critical damage to even make said armor effective (Other wise armor would be just be a capped dmg reducer)
and Critical hits happening 100% of the time once you reach a certain skill level of 6+ with decent stats is unrealistic really (Criticals should have a set cap of 70%-80% from happening).
Also in regards to arrows the fix simulates realism and simply carving a pointed skewer like arrow with wood and nothing to support it (fire hardening,fletches,arrow head) will not do much dmg even if you stab something with that skewer like thing hence the change to fletching of arrows.
It fixed the factor that you won’t be able to abuse it that early and not take out the difficulty fun because starting too powerful early takes out fun faster.
Anyway if you noticed New special arrows have been added just to offset the difficulty of creating arrows, once you make Flammable arrows and use a lighter to turn them into novelty Flaming arrows (It will set a target on fire better than any incendiary round could ever do cause it isn’t a 1in4 chance for flesh type)
Similarly plans regarding weapons (Yes Melee weapons included which means unarmed gloves with effects) would be making new specialty effect ones which produces electric,fire,acid,freezing dmg.
